TOOTH BRUSH AND POLISHER Filed April 29, 1930 Patented Nov. 24, 1931 PATENT OFFICE.

HARRY R. PRIEST, OF LOUDONVLLE, OHIO TOOTH BRUSH AND POLISHER Application filled April 29,

This invention relates to tooth brushes and polishers and has for an object to provide a fountain tooth brush and polisher that may be carried on the person and contain a large supply of cleansing material.

A further object of the invention is to provide a tooth brush and polisher of this type which will be small and compact so that it will take up a comparatively small amount 1o' of space when not in use and in which both the tooth brush and the polisher will be adequately housed and protected from dust and contamination. y N 'A still further object is to provide a tooth brush and polisher in which the tooth brush component is provided with a substantially conical tufted bristle portion which will readily enter between the teeth during the ybrushing operation and 'will more thoroughly 201L brush the teeth than hitherto possible.

A still further object is to provide a tooth brush component with a ieXible rubber skirt which encircles the tufted conical brush and lis sufficiently flexible to massage the gums and promote a healthy condition thereof without injury to the gums during the brushing operation.

A still further obj ect of the invention is to .provide a combined tooth brush and polisher having a handle portion terminally equipped with caps for protecting the polisher and the brush and which have flat ends to permit of the handle being stood on end.

A still further object is to provide a combined tooth brush and polisher having the handle portion so constructed as to keep the polisher or the brush away from a supporting surface when the handle is laid on its side.

A still further ob] ect is to provide a fountain tooth brush and polisher which also is equipped with a mirror in one end thereof to permit of inspection of the teeth.

I lith the above and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the 5U lscope of the appended claims without depart- 1930. Serial No. 448,382.

parts, 10 designates in general the handle of i? the combined tooth brush and polisher, the same comprising a hollow section 11 and a hollow section 12, the section 11 being provided with an elongated reduced neck 13 which is eXteriorly provided with screw threads 14 to receive the interior screw threads 15 of the section 12. The section 'l2 is closed at one end as shown at 16 and is threaded to receive a cap 17, the outer face of which is flush with the outer face of the 5* section 12. The section 11, however, is open at both ends and at the end opposite the neclr is provided with a fiange 18 which is preferably formed smooth to receive a cap 19 the inner face of which frictionallj,7 engages with the outer face of the section 11. Said flange is also interiorly threaded to receive the tooth brush component which will now be described.

The tooth brush component comprises an enlarged cylindrical base portion 2O which is threaded eXteriorly at one end as shown at 21 to receive the interior screw threads 22 on the flange 18. The base portion is axially extended to form a substantially concave disc 23 to provide a finger hold for exerting pressure on the brush. The underneath face of the disc is provided with a counter-sink 24 and furthermore both the disc 23 and base portion 20 are axially bored out to provide a channel 25. The channel opens through the end of the base portion in an enlarged flared intake mouth 26, and opens through the center of the counter-sink 24 to provide an outlet nozzle 27.

For promoting the effective brushing of the teeth downward and especially to provide adequate means for brushing the spaces between the teeth, there is provided a substantially conical tuft of bristles designated in general by the numeral 28, the bristles preferably being of the type known as badger vbristles which are'known to possess longlife under severe conditions of service. The tuft is arranged as an integral unitary structure in a rubber base 29 which snugly lits inthe counter-sink 24 and is provided with a central opening 30 that registers With the noz-'- Zle 27 above described.

The conical shape of the t'uftedbrusli component permits entry of the same into. thel spaces between contiguous teeth so. that a more thorough'downward- (from` gum inarto biting edge) brushing can be accomplishedthan-hitherto possible;

In order that the gumsmay be massaged aiidltheir healthy condition promoted'. during the brushing operation, a resilient iieX ible rubber skirt 31, substantially of annular form, is secured at one edge in a recess 32l formed in the rubber-base129`- The skirt surrounds the edges of the bristles and is of. suiiicient length to extend to substantially one half the length. of thelongest Ybristles as clearly shown.v Inl additionv to- Vrubbing against. the gums duringtherbrushing operationl and thus gently' massaging the. gums,, the skirt permits the function of holding the bristles in a compact unit.

By again. referring to Figure y2 it will be A seen that the polishing: component of the combined tooth brush and polisher coinprises a yoke 324 the base of, which is provided with. a lugl Sfwhic'histhreaded into an axialy opening in the'closed. end 16 of the Vhandle section 12. A shaft 34s connects the branches of the yoke and on the shaft isliXed. acircular polisher 35; The polisher'iscomposed of comparatively stiff. fibrous material arranged inthe formof an annular and confined in asuitable cylindricalxbase 36..

In order that thev teeth may be inspected theV end? vvalll of the cap 17. isprovided-witli al counter-sink in which there is disposed: a` mirror 37- and if; desired this mirror may be slightly convex` tofenlarge thel image; In operation, thev hollow handle 10 is preferably filled with the cleansing material` such as dental cream.v The section 1.2: of the handle may be advancedon-the threaded neck 14 to'feed the dental creamthrough the ch an nel 25'and opening() totliebristles 28.

' It willi be observedy that by virtuev of the'v ponent, these components willV be protected from contact and therefore contamination-V when the device is.; laid; onV its side on a sup'- port.

Vzine to saidtuft'.

It will be further observed that by virtue of the ends of the caps 17 and 19 being fiat the device may be stood on either end when desired. It will be still further observed that the brush component, polisher component, and mirror are all compactly assembled in a single unitary structure which will` occupy only. a small' space whennot in use.

Both caps 17 and 19 are provided'with vents 39 to permit drying out of the brush and. polisher wheni Wet. 1

Having thus described the invention, I claimt 1. A tooth cleaning device having the appearance of a fountain penand comprising relatively movable tubular sections forming ay magazine for tooth paste,.a disk depressed. on the upper'face to provide a finger hold for applying pressure thereto, a. single unitary short tuft ofV comparatively stiffv bristles centralized in thef bottom face of the disk underneath the depression, a. shankintegral with the disk. and. of less length: than the. diameter of the disk, a threaded plug base. integral with. the .shank and disposed' at a. right angle to the disk,l said plug being threaded.l into the end of one of said tubular sections, said shank and said plug having an axial duct. for vdelivering tootlipaste from the magazine to they bristle tuft, and, aremovable cap on the last-named. section, Vthe other of said sections being of the same outer diameter as said. removable cap to impart the. appearance of a fountain pento the article..

2. A tooth cleaning devicecomprising a magazine for toothpaste, a shortaxial hol-V low. shankprojecting from. the magaz'ineand rterminating ina disk. having a depressionin theupper face to provide a. fingerrhold for applying pressure tothe disk, a circular softrubberskirt projecting fromthe bottom face of the disk underneath said depression, and' a single unitary short tuft of comparatively stiff bristles Vembedded in the bottom face of 'die disk concentric with the skirt andi of slightlyy greater length than the length of the skirt, there being a sectional duct in saidI shank to conduct'tooth paste from the'maga- 3. A device'of'the classdescribed' comprising a. hollow handle including relatively movable sections, a tooth brush component" carriedl by one j of said' sections, a polisher carried by the other section, and' caps onY said sections housing said.v tooth brush componentv and said polisher.

In testimonyv wherof. I affix my signature.;l
